Document Summary

Lecture 6e what regulates life in the world ocean: competition, shared resources (same resource used by multiple populations), limited resources and required resources (no other viable local resources to use) all cause competition. Without one of these conditions, competition is unlikely: most of these conditions are met in pelagic plankton with respect to nitrogen, phosphorous and other micronutrients such as silica, iron and manganese. Below this level, the species cannot survive: for 2 or more species, each species has a competitive ability with respect to each nutrient (ability to take up nutrients and turn into more plankton) If species 1 is a better competitor for a and b, then species 1 will dominate and species 2 will go extinct. If each species is a good competitor on alternate resources (1 good for b, 2 good for a), the two species may coexists.
